United States Patent 3,132,894 RECLINER CHAR OF THE MULTIPLE POSITIONTYPE IN CORPORATING IMPROVED HEAD- REST CONTROL Fridtjof F.Schliephacke, Berlin-Schmargendorf, Germany, assignor to Anton Lorenz,Ocean Ridge, Boynton Beach, Fla.

Filed Aug. 30, 1960, Ser. No. 52,943 3 Claims. (Cl. 297-61) The presentinvention relates generally to reclining chairs of the multiple movementtype, and in particular to an improved head-rest and mounting andcontrol arrangement for such reclining chairs.

The recently developed multiple movement chair comprises a support andbody-supporting means including a seat and back-rest which is mounted onthe support for movement from a sitting position to an intermediate,tilted sitting position during a first movement phase and for movementfrom the intermediate, tilted sitting position to a reclining positionduring a second movement phase. Such chairmay be of the reclining typeincluding a movable seat and a movable back-rest in which the seat andback-rest move with substantially no change in their angularrelationship during the first movement phase and move with an increasein the angular relationship therebetween during the second movementphase; or may be of the rester type including a rigid seat and back-restin which there is no change in the angular relationship between the seatand back-rest during either of the movement phases. Such multiplemovement chairs of the recliner or rester type usually incorporate aleg-rest which is mounted for movement into a substantially elevatedleg-supporting position during the first movement phase such as toprovide an adequate leg-support for the chair occupant in theintermediate, tilted sitting position and in the infinite number ofreclining positions during the second movement phase. Further, suchmultiple movement chairs may incorporate a head-rest which is mountedfor movement on the back-rest from a stored position to an extendedhead-supporting position during the first movement phase such as toprovide an adequate head-support for the chair occupant in theintermediate, tilted sitting position and in the infinite number ofreclining positions during the second movement phase. The incorporationof the head-rest in the chair facilitates modern styling, enabling thecomfort requirements to be realized in a chair having a relatively lowback.

Broadly, it is an object of the present invention to provide an improvedhead-rest and mounting and control arrangement adapted to beincorporated into a multiple movement chair of the recliner or restertype. Specifically, it is within the contemplation of the presentinvention to provide a head-rest which is moved to an extendedhead-supporting position in response to the first movement phase of themultiple movement chair of the recliner type such that during the secondmovement phase, as the angle between the seat and back-restprogressively opens up, the head-rest is in its head-supporting positionand remains stationary relative to the back-rest for the head-supportingfunction.

It is a further object of the present invention to pro vide an improvedmounting arrangement for movably mounting a head-rest on a back-rest formovement between a stored position within the outline of the backrest toan extended head-supporting position spaced above and forwardly of theback-rest.

In accordance with an illustrative embodiment demonstrating objects andfeatures of the present invention, there is provided a reclining chairwhich comprises a support, body-supporting means including a seat andback-rest adapted to be mounted on the support for movement from asitting position to an intermediate, tilted sitting position during afirst movement phase and from the intermediate, tilted sitting positionto a reclining posiion during a second movement phase, and coordinatingmeans operatively connected to the bodysupporting means and mounted onthe support for establishing the first and second movement phases whichcoordinating means includes a pivotal mount on the support about whichthe seat turns during the second movement phase. A head-rest is mountedon the back-rest for movement from a stored position to an extendedhead-supporting position during the first movement phase, and actuatingmeans are operatively connected to the mounting means for the head-rest,to the body-supporting means and to the support for moving the headrestto the extended supporting position during the first movement phase ofthe chair. The actuating means includes a displaceable pivot on thebody-supporting means which is movable relative to the pivotal mountduring the first movement phase and is movable substantially in an areabout said pivotal mount during the second movement phase. The relativemovement of the displaceable pivot causes a movement of the headrest tothe extended supporting position during the first movement phase; andthe arcuate movement of the displaceable pivot maintains the head-restsubstantially in the head-supporting position during the second movementphase.

In accordance with further features of the present invention, themounting means for the head-rest includes a first mounting link which ispivotally mounted on the back-rest at a first pivotal mount andpivotally connected to a head-rest at a first pivotal connection and amounting link pair which includes second and third mounting links whichare pivotally interconnected. Provision is made for pivotally mountingthe second mounting link on the back-rest at a second pivotal mountspaced from the first pivotal mount and for pivotally connecting thethird mounting link to the head-rest at a second pivotal connection at apoint spaced from the first pivotal connection. By appropriatelyproportioning and arranging the several mounting links, it is possibleto establish varying paths of movement for the head-rest and to orientthe head-rest in a wide variety of head-supporting positions relative tothe back-rest wherein the head-rest remains during the second movementphase.

The above brief description as well as further objects, features andadvantages of the present invention will now be described by referenceto the following detailed description of a presently preferred, butnonetheless illus trative, embodiment according to the presentinvention, when taken in conjunction with the accompanying drawings,wherein:

FIG. 1 is a side elevational view of a typical multiple movementrecliner type chair incorporating an improved head-rest and mounting andcontrol arrangement in accordance with the present invention, thehead-rest being shown in its retracted or stored position and the chairbeing shown in its sitting position;

FIG. 2 is a side elevational view similar to FIG. 1 but with theportions of the frame removed in the interest of clarity, the head-restbeing shown in its extended head-supporting position and the chair beingshown in an intermediate, tilted sitting position; and

FIG. 3 is a side elevational view similar to FIG. 2, showing thehead-rest remaining in its extended headsupporting position, the chairhaving moved through the second movement phase into a fully reclinedposition.

Referring now specifically to the drawings, there is shown a recliningchair 10 which embodies an improved head-rest and control arrangement inaccordance with the present invention. The chair 10 is constructed inaccordance with the teachings of US. Patent No. 3,065,026, filed on July20, 1960, now Patent No. 3,065,026, granted November 20, 1962, andentitled Reclining Chair of the Multiple Position Type, and includes achair frame or support 12 having opposite side walls 14, 16interconnected by appropriate cross braces 18 and supported on dependinglegs 20. A body-supporting unit or means including a back-rest 22 and aseat 24 are mounted on the support for reclining and inclining movementrespectively through a first movement from the upright sitting positionillustrated in FIG. 1 to the intermediate, tilted sitting positionillustrated in FIG. 2 and for a second movement phase from theintermediate, tilted sitting position illustrated in FIG. 2 through aseries of reclining positions to the fully reclined po sitionillustrated in FIG. 3. Although, the back-rest is adapted for movementrelative to the seat during the second movement phase, it will beappreciated that the invention herein finds application in rester typechairs including a unitary body-support means. In the interest ofsimplicity there is no showing the'leg-rest and its mounting arrangementwhich is usually found in reclining chairs of this type.

The back-rest 22 is mounted on the seat 2-4 at a backrest pivot 26 whichback-rest pivot is provided intermediate the seat and an elongatedback-rest bracket 28 which is secured to the lower end of the back-rest22 and extends fore and aft of the chair. Extending from the front tothe rear of the chair frame or support 12 is a first carrier member 30which rests adjacent its front end on an adjacent and underlying crossbrace 18 and has a first carrier pivot 32 at its rearward end on thesupport provided by an appropriate mounting bracket 34. During the firstmovement phase, the first carrier member 30 remains stationary and restsagainst the underlying cross brace 18, as may be appreciated byprogressively inspecting FIGS. 1 and 2; and during the second movementphase the first carrier member 30 turns in the clockwise direction aboutthe first carrier pivot 32 and through an ascending arc, as may beappreciated by progressively inspecting FIGS. 2 and 3.

Seat guiding means are operatively connected between the first carriermember 30 and the seat 24 for imparting a first inclination to the seat24 during the first movement phase, as may be seen in FIGS. '1 and 2.The seat guiding means includes a front seat guiding link 36 which isupwardly and forwardly inclined from its lower end to its upper end. Thelower end of the front seat guiding link 36 has a front pivotal mount 38on the forward end of the first carrier member 30, while the upper endof the front seat guiding link 36 has a front pivotal connection 4th tothe seat 24. Disposed rearwardly of the front seat guiding link 36 andsubstantially parallel thereto is a rear seat guiding link 4-2 which hasa rear pivotal mount 44 at its lower end on the first carrier member 30at a point spaced rearwardly of the front pivotal mount 68 and a rearpivotal connection 46 to the seat 24 at a point spaced rearwardly of thefront pivotal connection 4-0. The front and rear gear guiding link 36,42 and the relatively stationary first carrier member 30 will berecognized as providing a four-bar seat guiding linkage which isoperative during the first movement phase to guide the seat 24reaiwardly relative to the support to an inclined position, with thefirst carrier member remaining stationary during such first'movementphase.

Provision is made for blocking movement of the seat guiding meansrelative to the first carrier member 3% at the end of the first movementphase such that the carrier member 30, the seat guiding means, and theseat 24 become a unitary assembly which turns about the first carrierpivot 32 during the second movement phase. The blocking means is in theform of a stop 43 which is fixed to the carrier member 30 rearwardly ofthe front guiding link 36 and in position to abut the same in theintermediate, tilted sitting position illustrated in FIG. 2.

The coordinating or guiding linkage for the chair is completed by theprovision of a second carrier member 50 which is disposed abovethe firstcarrier member 30 and extends from front of the chair frame or supportto a location rearwardly of the first carrier pivot 32. At its rearwardend the second carrier member 54 has a second carrier pivot 52 on thesupport provided by an appropriate mounting bracket 54 which secondcarrier pivot 52 is spaced rearwardly of the first carrier pivot 32.Means are provided for connecting the second carrier member 50 to theback-rest 22 which means is arranged in relation to the seat guidingmeans for guiding the backrest 22 to a first reclined position duringthe first movement phase, with the second carrier member 50 remainingstationary. The connecting or coupling means includes a back-restconnecting and guiding link 56 which is upwardly and forwardly inclinedand is generally parallel to the front and rear seat guide links 36, 42.The back-rest connecting and guiding link 56 has a pivotal connection 53at its lower end to the forward end of the second carrier member 50 andhas a pivotal connection 60 at its upper end 'to the forwardly extendingelongated back-rest bracket 23.

Provision is made for coupling the second carrier member 50 to the firstcarrier member 30 such that during the second movement phase the firstcarrier member 38 serves as a driver lever while the second carriermember 50 serves as a driven lever. The coupling means includes acoordinating link 62 which has a first coordinating pivot 64 to thefirst carrier member 30 at a point spaced from the carrier pivot 32 anda second coordinating pivot 66 to the second carrier member 50 at apoint spaced from the second carrier pivot 52. The first carrier member30 intermediate the first coordinating pivot 64 and the first carrierpivot 32 provides the driver lever, while the second carrier member 5%intermediate the second coordinating pivot 66 and the second carrierpivot 52 provides the driven lever. The effective length of the driverlever is longer than the driven lever such that the angular displacementof the driven lever is greater than the corresponding angulardisplacement of the driver lever during their concurrent movement.Accordingly, for each increment of turning movement of the driver lever,there is a corresponding greater turning movement or angulardisplacement of the driven lever such that there is an increase in theangular relationship between the seat.24 and the back-rest 22 during thesecond movement phase. The ratio of the effective lever arms providedrespectively by the first and second carrier members 30, 50 is selectedto establish the desired increase in the angular relationship betweenthe seat 24 and the back-rest 22. during the second movement phase, asmay be appreciated by comparing FIGS. 2. and 3. At the start of thesecond movement phase and in the intermediate, tilted sitting positionof FIG. 2 it is seen that the first and second carrier members 30, 50are substantially paralleL w hile at the end of the second movementphase (as seen in FIG. 3), the second canrier member 50 has turnedthrough a greater angular traverse about the second carrier pivot 52 ascompared to the first carrier member 30 which turns about the firstcarrier pivot 32. Since the seat 24 is effectively unitary with thefirst carrier member 3;) throughout the second movement phase and theback-rest 22 is coupled to the second carrier member 563 there is acorresponding increase in the angular relationship between the seat andback-rest incident to the accelerated turning of the second carriermember 50 in relation to the first carrier member 36. p

In order to facilitate a more thorough understanding of the environmentfor a head-rest and control arrangement according to the presentinvention, a typical sequence of operations of the described reclinertype of chair follows:

When the chair occupant is seated in the body-supporting unit 22, 24 andleans against the back-rest 22, the first movement phase is initiatedwith the sea 24 being guided relative to the stationary first carriermember 30 to the first intermediate, tilted sitting position. Duringsuch first movement phase, the second carrier member 50 which is coupledto the first carrier member 30 remains stationary with the back-rest 22being guided by the back-rest connecting and guiding link 56 turningabout its pivotal connection 58 to the second carrier member 50 as arelatively stationary back-rest pivot. The guiding action of the link 56will be such as to maintain a substantially fixed angular relationshipbetween the seat 24 and the back-rest 22 in that the link 56 issubstantially parallel to the front and rear seat guiding links 36, 42.When the front seat guiding link "36 abuts the stop 48 at the end of thefirst movement phase and as the chair arrives at the intermediate,tilted sitting position, the unitary relationship is established betweenthe seat 24 and the first carrier member 34) such that the assembly ofthe seat, the intermediate seat guiding means and the carrier member 39turn about the first carrier pivot 32 during the second movement phase.Upon further pressure against the back-rest, there will be a concurrentclockwise turning movement of the first and second carrier members 31),50 through ascending arc about their respective first and second carrierpivot 32, 52, with the second carrier member having a greater turningmovement than the first carrier member due to the coordinatinginterconnection 62 therebetween. Accordingly, the back-rest is reclinedat a greater rate than the seat is inclined to open up the angle betweenthe seat and back-rest during the second movement phase and as the chairmoves through the infinite number of reclining positions to the fullyreclined position illustrated in FIG. 3.

Disposed within the upper end of the back-rest 22 is a head-rest 70which is mounted on the back-rest 22 for movement from a stored positionillustrated in FIG. 1 to an extended head-supporting position, shown inFIGS. 2 and 3. The mounting arrangement for the head-rest 70, which isgenerally designated by the reference numeral 72, includes a firstmounting link 74 which is pivotally mounted at a first pivotal mount '76on the back-rest 22 and is pivotally connected at a first pivotalconnection 78 to the head-rest 79. The mounting arrangement 72 furtherincludes second and third mounting links 811, 82 having an intermediatepivotal connection 84. The second mounting link 80 of the mounting linkpair 81 82 has a second pivotal mount 86 on the back-rest 22 at a pointspaced below the first pivotal mount 76, while the third mounting link82 has a second pivotal connection movement phase and which movessubstantially in an arc about the pivotal mount 32 during the secondmovement phase. As will appear hereinafter, the relative I movement ofthe displaceable pivot 26 away from the 38 to the head-rest 70 at apoint spaced below the first pivotal connection '78. By appropriatearrangement and dimensioning of the several mounting links 74, 80 and82, it is possible to establish a path of movement for the headrest 70relative to the back-rest 22 such that the head-rest may be brought to aclearance position relative to the back-rest and then to the desiredattitude relative to the back-rest for the head-supporting function.

Actuating means are operatively connected to the mounting arrangement orlinkage 72, to the body-sup porting means 22, 24 and to the support 12for moving the head-rest 70 from the stored position illustrated in FIG.l to the extended head-supporting position illustrated in FIGS. 2 and 3.The actuating means or mechanisms includes a displaceable double-armlever 90, illustrated herein as a plate which is pivotally mounted onthe body-supporting means 22, 24 at a displaceable pivot. In thisillustrative embodiment, the displaceable doublearm lever 90 ispivotally mounted coaxially of the backrest pivot 26, with the back-restpivot 26 serving as the displaceable pivot which moves relative to thesupport 12 and away from the pivotal mount 32 during the first pivotalmount 32 during the first movement phase causes a movement of thehead-rest 70 to the extended headsupporting position; and the arcuatemovement of the displaceable pivot in a radius substantially about thepivotal mount 32 during the second movement phase maintains thehead-rest 70 substantially in the extended head-supporting position.

The actuating means or mechanisms further includes a pivotally mounteddouble-arm lever 92 which is mounted intermediate its ends at a fixedpivot 94 provided by appropriate mounting bracket 96 such that thedoublearm lever 92 may turn about the fixed pivot 94. The displaceabledouble-arm lever has an upwardly directed relatively short arm which iscoupled by a connecting link 98 to a relatively short arm of thedouble-arm lever 92. Specifically, the connecting link 98 has a pivotalconnection 160 at its lower end to the displaceable doublearm lever 99at a point spaced from the displaceable pivot 26 thereof and has apivotal connection 102 at its upper end to the relatively short arm ofthe double-arm lever at a point spaced from the fixed pivot 94 thereof.The longer arm of the displaceable lever 90 has a pivotal connection 104to the upper end of an actuating link 106 which has an actuating pivoton the support 12 which is coaxial with the pivotal mount 32 for thefirst carrier member 30. The longer arm of the double-arm lever 92 isconnected to the mounting arrangement 72 by a connecting link 108 whichhas a pivotal connection 110 at its lower end to the longer arm of thedouble-arm lever 92 and has a pin and slot connection to the secondmounting link 81) provided by a pin 112 fixed to the connecting link 1%and confined within an arcuate slot 114 formed in the second mountinglink 81). The link 108 has a pivotal connection 116 at its upper end tothe mounting link 74.

In order to facilitate a more thorough understanding of the operation ofthe improved head-rest and mounting and control arrangement illustratedherein, a typical sequence of operations of the head-rest will now bede: scribed;

When the chair occupant is seated in the body-supporting means 22, 24and urges his or her weight rearwardly, the chair moves through thefirst movement phase, from the sitting position illustrated in FIG. 1 tothe intermediate tilted sitting position illustrated in FIG. 2 duringwhich the displaceable pivot 26 and the head-rest actuating mechanismsor means moves away from the pivotal mount 32 and the carrier member 3%it being recalled that the carrier member 30 remains stationary duringthe first movement phase. Incident to the movement of the displaceablepivot 26 and due to the constraining effect of the actuating link 106,there is a concurrent turning movement of the double-arm lever 90 in theclockwise direction about the displaceable pivot 26 which is movingrearwardly and downwardly. The movement of the displaceable double-armlever 90 turns both the long arm intermediate the pivots 26, 104 and theshort arm intermediate the pivots 26, in the clockwise direction whichexercises a downwardly directed pull on the connecting or coordinatinglink 98. This downwardly directed pull turns the relatively short armintermediate the fixed pivot 94 and the pivotal connection 102 of thedouble-arm lever 92 in a clockwise direction and concurrently turns thelong arm intermediate the fixed pivot 94 and the pivotal connectionupwardly in a clockwise direction. The ratio of the short and long armsof the double-arm lever 92 is such as to magnify the turning movementimparted thereto, which magnified movement is imparted by the connectinglink 108 to the mounting arrangement or linkage 72 to turn the mountinglinks 74, 80, 82 upwardly and forwardly about their respective pivotalmounts 76, '86 on the back-rest 22. Such upward movement of the mountinglinks, turning in the counterclockwise direction, brings the head-restill to the extending head-supporting position at the end of the firstmovement phase, as shown in FIG. 2. In such extended head-supportingposition, the actuating link 1% and the long arm intermediate thedisplaceable pivot 2s and the pivotal connection of the double-arm lever9b are substantially in alignment with each other such that these linkstogether may be considered to be a single link intermediate the pivotalmount 32 for the carrier member 36 and the displaceable pivot 2i).Accordingly, during the second movement phase, when the seat 24 iseffectively a unitary assembly with the carrier member 3% turning aboutthe carrier pivotal mount 32, the displaceable pivot 26 turns in an areabout the pivotal mount 32, as the back-rest is reclined. There issubstantially no tendency for the dispiaeeable double-arm lever 9t) toturn about the pivot 26 through the second movement phase, as may beappreciated by progressively inspecting the position of the lever t) inthe limit positions of FIGS. 2 and 3. Accordingly, substantially noturning movement is imparted to the lever 92 and the head-rest 70remains in the desired head-supporting position throughout the secondmovement phase. Although it is preferred to coaxially mount theactuating link 106 on the pivotal mount 32 for the carrier member 3%, itwill be appreciated if the pivotal mount for the actuating link 1% weredisplaced forwardly of the carrier pivotal mount 32 on the carriermember 30, there would be a tendency for the head-rest 76 to movesomewhat forwardly during the second movement phase from the illustratedposition of FIG. 2. Conversely, if the pivotal mount for the actuatinglink 1% were displaced rearwardly on the carrier member 31') in relationto the pivotal mount 32, there would be a tendency for the head-restI'll to move rearwardly from the illustrated position of FIG. 2 in thesecond movement phase. As required, the actuating arrangement for thehead-rest may be arranged to automatically produce minor adjustments ofthe head-rest relative to the back-rest during the second movementphase.

Although the invention has been illustrated in its specific applicationto a recliner type of multiple movement chair, it will be appreciatedthat invention finds application to a tester type of multiple movementchair including a unitary seat and back-rest wherein during the firstmovement phase the body-supporting unit moves relative to a prescribedpivot to bring about an actuation of the head-rest and during the secondmovement phase there is a turning movement about such pivot, whichmaintains the head-rest in a relatively fixed position in relation tothe back-rest.

A latitude of modification, change and substitution is intended in theforegoing disclosure and in some instances some features of theinvention will be employed without a corresponding use of otherfeatures. Accordingly it is appropriate that the appended claims beconstrued broadly and in a manner consistent with the spirit and scopeof the invention herein.
